IMPROVEMENT IN PLows.

Specification forming part of Letters Patent No. 201,222, dated March12, 1878; application filed June 11, 1877.

To all whom it may concern:

Be it known that we, PATRICK H. BURNs and WILLIAM G. MOELHANY, of thecity and county of Indiana, and State of Pennsylvania, have invented anew and useful Improvement in Flows, of which the following is aspecification:

Figure 1, Sheet 1, is a view of the moldboard side of our improved plow.Fig. 2, Sheet 1, is a view of the land-side side of our improved plow.Fig. 3, Sheet 1, is a front view of our improved plow. Fig. 4, Sheet 2,is a detail view of the land-side side of the standard. Fig. 5, Sheet 2,is a detail view of the mold-board side of the standard. Fig. 6, Sheet2, is a detail view of the outer side of the land-side. Fig. 7, Sheet 2,is a detail View of the inner side of the land-side. Fig. 8, Sheet 2, isadetail view of the land-side side of the point. Fig. 9, Sheet 2, is adetail view of the mold-board side of the point.

Similar letters of reference indicate correspending parts.

The invention will first be described in connection with the drawing,and then pointed out in the claim.

In the drawing, A represents the plow-beam, which rests upon and issecured to the head formed upon the upper end of the standard B by abolt and nut. The standard B is bent or curved, making its land-sideside convex, and its mold-board side concave. Upon the convex side ofthe standard B is formed a seat for the inner side of the forward partof the landside 0, and its forward edge has a notch, 1), formed in it toreceive a flange, c, formed upon the inner side of the forward end ofthe landside 0. The land-side O is secured to the standard B by bolts,the nuts of which rest in recesses or countersinks formed in themoldboard side of the said standard B, and which are covered by thepoint D. The land-side O is curved longitudinally, so as to be roundedor oonvexed upon the outer side. The lower part of the outer side of theland-side (lis rabbeted, or has an offset formed in it, to 'receive thedetachable land side E, which is curved or convexed to correspond withthe curve or convexity of the main land-side O, and its lower edge isturned in beneath the lower edge of said land-side O, to bear upon thebottom of the furrow and take the wear. The point D is made concave uponthe moldboard side and convex upon the land-side side, and has its upperend beveled off to abut against and fit upon a shoulder formed upon theupper part of the standard B. The point D rests upon and covers theforward end of the land-side O, is bolted to the standard B,

and its forward edge and the forward edge of the upper part of thestandard B form the colter. The forward end of the .point D is madegouge-shaped, or concave upon the upper side and convex upon the lowerside.

F is the mold-board, the forward end of which, abuts against the pointD, and against a shoulder formed upon the standard B, and is bolted tosaid standard. The mold-board F is concaved longitudinally to correspondwith the curvature of the standard B, the whole plow being thusgouge-shaped. M is the share, which is made separate, is bolted to thestandard B, and abuts against the edges of the point D and themold-board F. Upon the inner side of the lower part of the share M isformed a lug, m, which rests against the lower edge of the mold-board F,to relieve the bolt from the strain. The rear ends of the mold-board Fand the land-side O are braced against inward pressure by a bar, G, theends of which are dovetailed, and are inserted in dovetailed lugs formedupon the inner sides of said mold-board and land-side. H are thehandles, which are connected by rounds, and the lower ends of which arebolted to the landside 0 and the mold-board F. The rear end of theplow-beam A is secured to the plate or casting I by a bolt, J, whichpasses through a hole in the beam A and a slot in the plate I, so thatby loosening the nut of the bolt J the beam A may be adjusted to causethe plow to take or leave land, as may be required. The ends of theplate I are flanged, and are bolted to the handles H.

Kis the cutter, the blade of which is curved to correspond with thecurvature of the landside 0. The shank of the cutter Kis straight, isinserted in a groove in the side of the clamp L, and is secured to saidclamp by a bolt. The clamp L is made U-shaped, and its arms overlap theupper and lower sides of the plow-beam A, and are slottedlongitudinally, to receive the bolt by which they are secured to thesaid plow-beam A, so that by loosening the nut of the said bolt thecutter K may be adjusted to correspond with the adjustment'of the plowto take or leave land. The cutter K has no Vertical adjustment, assuchan adjustment would prevent the curvature of the cutter fromcorresponding with the curvature of the landside 0.

Having thus fully described our invention,

we claim as new and desire to secure by Letters Patent- The standard B,made convex on one and concave on the other side, notched andshoulderedtoreceivetheland-side,mold-boardpoint, and share, and incombination therewith, as shown and described.
